Standard electrode potential Au^(+3)//Au...

Standard electrode potential `Au^(+3)//Au` couple is 1.428 V and that for `Na^(+)//Na` couple `-2.714 V` These two couples in their standard state are connected to make a cell. The cell potential will be :-

A

4.142

B

1.286V

C

`-1.286 V`

D

`3.376 V`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(cell)^(@)=E_(R.P.)^(0)(cathode)-E_(R.P)^(0)(Anode)`
`1.428-(-2.714)`
`=4.142V`
